We have been given that distance from Kevin's home to his school is 2 kilometers.
We know that 1 kilometer is equal to 1000 meters.
Hence, distance between Kevin's home to his school is 2000 meters.
Now, we have been given that Adrian lives 750 meters from the same school.
Therefore, the difference is the distance is given by
[tex]2000-750\\ \\ 1250 \text{ meters}[/tex]
Therefore, Adrian live 1250 meters close to the school than Kevin.
A is the correct option.
